The car-free event on Sept. 24, organized by the city's Office of Transportation and Infrastructure Systems (OTIS), brought an estimated 30,000-40,000 people to South Street stretching from the Delaware River to the Schuylkill River.

Bikers, runners and pedestrians filled the streets to take advantage of a pilot expansion to the city's traditional closure of Martin Luther King, Jr. Drive, first introduced in 1994 to promote active transportation and healthy lifestyles.

On Friday, OTIS released the findings of an initial survey of 600 people who participated in the Saturday event. Their impressions were overwhelmingly positive.

The survey found that a full 42 out 47 Philadelphia zip codes were represented in the event. Among all participants, 61 percent were from Philadelphia, 23 percent were from an unknown origin, nine percent came from Pennsylvania cities other than Philadelphia and six percent came from other states.

Among the 600 people surveyed, 64.3 percent of respondents engaged in outdoor activity that otherwise would not have occurred without Philly Free Streets. The event also attracted people of all ages, with a slight lean in favor of women.

Data from survey on 2016 Philly Free Streets event.

From a diversity standpoint, 27 percent of respondents identified as non-Caucasian, including 17.2 percent reporting as African-American.

Among those who participated, data from app sponsor Vea Fitness found that walkers and runners averaged about 2 miles in distance traveled, compared to four miles for cyclists.

“Philly Free Streets was a fabulously successful event,” said Joe Syrnick, Executive Director of the Schuylkill River Development Corporation. “Many of those on the Schuylkill Trail on September 24th were there because of the event, and had never been to the trail before. So it is clearly teaching people about the joys of the trail, and of active transportation. Many of them told me they hope Philly Free Streets will become a regular event – and we here at SRDC fully agree."
